OBJECTIVE This study evaluated the fracture strengths of endodontically treated teeth restored with prefabricated posts with different post lengths. MATERIAL AND METHODS Thirty freshly extracted canines were endodontically treated. They were randomly divided into groups of 10 teeth and prepared according to 3 experimental protocols, as follows; Group 1/3 PP: teeth restored with prefabricated ...

INTRODUCTION The aim of this study was to evaluate the effects of bleaching gel using 35% hydrogen peroxide (HP), associated with red carmine pigment (RC), in the 3:1 or 1:1 ratio, on fracture resistance and dentin microhardness of endodontically treated teeth. MATERIALS AND METHODS A total of 40 lower incisors were endodontically treated and divided into four groups (n = 10), according to th...

UNLABELLED The aim of this study was to evaluate the incidence of intraradicular retention and the prevalence of different types of posts used for the restoration of endodontically treated teeth, in clinical practice. MATERIALS AND METHODS The study was performed on 94 digital panoramic radiographies that allowed a comprehensive appreciation. Root canal fillings and the posts were identified ...

Dentists often place post and core buildups on endodontically treated abutments for crown and bridge restorations. This article analyzes the bio-mechanical purposes, advantages and disadvantages of placing a core or a post and core in an endodontically treated tooth and reviews literature on post and core biomechanics. The author assesses the scientific rationale of the claim that the main purp...

Autogenous dentin has been reported to be a suitable grafting material for certain indications. The purpose of this study was assess the feasibility using endodontically treated teeth application. In present retrospective study, one-stage augmentation lateral ridge defects with shell and particulate (tooth technique (TST)) either obtained from (ETT, 17 patients 21 implants) or non-endodonticall...

Introduction. Endodontically treated teeth are usually weaker due to the loss of tooth structure. As most crown is destroyed, common retention for restoration application a fiber-reinforced composite posts in root canal. In endodontically teeth, there two main problems restorative procedure: reduced resistance remaining structure and choosing necessary adequate restoration. The aim this work wa...

Introduction: Post and core has been considered for endodontically treated tooth, especially in cases with severe damage crowns. Recently fiber reinforced composite posts (FRC post) have been used in the treatment of endodontically treated teeth. Because the length and diameter of posts are effective in stress distribution, the purpose of this study is to evaluate the effect of length and diame...

Endodontically-treated teeth are prone to fracture due to loss of tooth structure and altered mechanical behaviors. The stability and rigidity of post-restored teeth, particularly in cases involving periodontal destruction, has not been adequately investigated. This study examined the influence of post material on teeth with simulated bone reduction by a multiparametric evaluation. Sixty extrac...

Intra-radicular loss of tooth structure in endodontically treated teeth poses a challenge. Available methods for treatment are cast post-core, intra-radicular resin reinforcement using composite resin followed by placement of prefabricated metal/fibre post (glass or carbon).This study is an attempt to investigate the validity of treatment of such teeth using above methods and evaluate which pos...

A referred patient presented with a lesion of endodontic origin located at the apex of tooth #27. The tooth had been endodontically treated and re-treated. A periapical radiograph revealed a close relationship between the lesion and the maxillary sinus. A cone-beam computed tomography scan confirmed that the lesion had invaded the sinus cavity. The treatment plan consisted of periapical surgery...
